fallo en el arranque de oh-my-zsh: __git_prompt_git status blocks

He instalado iTerm2 y brew. En el proceso, tengo algunos problemas con mi terminal. No muestra nada a pesar de las órdenes que le doy. Lo único que puedo hacer es /bin/bash para volver a bash. También aparece -tail delante del zsh. ¿Cómo cambiar el zsh de nuevo a la normalidad?

¿Podría alguien echar una mano con esto? Sólo quiero embellecer mi terminal. Se lo agradezco mucho.

Esta es la secuencia después de pulsar Ctrl-C .no puedo introducir nada, todavía. Y presiono Ctrl-D muestra esto.

La ventana se quedó ahí. El problema se mantiene si la vuelvo a abrir.
